Environmental pollution is the major problem of the people living in industrialized areas. Seasonal variations of physico-chemical and Polycyclic aromatic hydrocarbon (PAHs) were studied in selected Rivers in Port Harcourt(Akpajo) and Aba, Nigeria, across the sampling points. Physico-chemical properties and PAHs were determined using standard methods and Atomic Absorption Spectrophotometer (AAS). Results showed that concentration of PAHs varies across two seasons (dry and rainy seasons) . The results of the seasonal variations showed Akpajo River gave highest recorded value of Anthracenedi-Benzyl(A-H)(0.21 mg/l) at station 1 with mean concentration (0.15±0.04) in dry season while the highest recorded value in rainy season was Anthracenedi-Benzyl (A-H)(0.25 mg/l) at station 3 with mean concentration(0.2163±0.03). Also, seasonal variations of Aba River gave the highest recorded value (Benzo [K ] Fluoranthene 0.1328 mg/l) at Point (Station) 1 with mean concentration
